Eastern Kentucky University has a program going up this fall for a 2 year online Fire Science BA program. However, they also have a 2 year online masters program in Safety, Security, and Emergency Management that will have a concentration in Fire and Emergency Services. (It also has concentrations in safety, security, homeland security, etc.)

I believe that some of University of MD's Fire Protection Engineering Masters is offered online, but I am not sure of the requirements (I am pretty sure you would already have to have a bachelors in some field of engineering).

Might I ask what are you intending to use the degree for. In other words, do you desire to be an design engineer (fire protection systems engineer) or do you just want a degree in fire science. The two are indeed different!
